A fully-licensed NSW motorcycle rider is filtering between two lanes of stopped traffic at 28 km/h. There is a school zone sign nearby but school hours have not yet started for the day. Is this filtering legal?

1. Yes — the school zone restriction on filtering only applies during operative school zone hours
2. No — lane filtering is always banned in any school zone area
3. Yes — fully-licensed riders can filter at any speed in a school zone
4. No — 28 km/h is too close to the 30 km/h limit to be safe and is automatically illegal
